To all whom it may concern:

Be it known that I, JOHN J. HEYs, a citizen ofthe United States, residing at Lynn, in the county of Essex, Commonwealth of Massachusetts, have invented an Improvement in Sole-Rounding Machines, of which the following description, 'in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention relates' to machines for shaping the soles ofpboots and shoes to the :approximate final ,form desired upon the cometed boot-or shoe. Machines of this type are known inthe art as sole rounding machines andV are designed tooperate u on a such others as will be readily understood byA roughly shaped sole generally, thougi not necessarily. having square ends, termed a sole blank, the machine in its operation rounding the ends and otherwise shaping the blank to the desired form.

The object of the present invention is to improve the eneral character of such ma'- chines, simpli y the construction thereof, andv provide for more effective operation upon the work all of which will more fully hereinafter a'pear'. l

To t e accomplishment of this object 'and those 'skilled in the art, the invention comprises the features and combination of parts ereinafter described and pointed out in appended claims. The" various features thereof will be best understood from a description of one ernbodiment thereof, such for instance as illustrated in the accompanying drawings,

, Referring to the drawingafFigure 1 is a vertical front to rear section, illustrating the machine selected for illustration herein;

In .the articular embodiment of my invention selected for disclosing my invention and shown in Figs. 1 to 11, inclusive, referling first to Fi s. 1 and 2, the frame A will beof any suitab e ordesired shape and construction, t being provided, as herein shown,

with bearings for a horizontal drive shaft a., having fast onits rear end the friction clutch member c. of said clutch member is the long hub a24 of the brake wheel a3, surrounding which (see Fast on the said shaft in frontv Fig. 8) is the band brake'a, secured to the frame. by a bolt y'. The band is provided with flaring ends d5, normally pressed onetoward the'other to cause the band tol grip the brake wheel by springs as, carried on a through andthrough-rodf. Loosely journaled upon the long hub 'a2 referred to, see Fig.H 1, `is the movable clutch.member as,

Threaded in the' bottom ofthe head a13 (Fig. 1) is the treadle rod fa, 'jointedat its lower end tothe short arm of the treadle lever als; the `treadle lever being loosely mounted ipon the treadle shaft a. and suitably secured, preferably by casting, in the frame.

- o ;l rounding head B (Figs.- Vl and 2), preferably detachable from the 'main frame'both for Upon the frame at its yfront side is the convenience of manuiacture and for repair.

. l @The top face oi this rounding head is smooth .and flat, t'o furnish a substantial bearing surface' for the horizontally movable or gyratory "knife carrier orhead b, shown se aratelyin Fig-6. This knife carrier (see lgs. 3 and 4) .is provided with' along slot b', in which Fig. 6. In the right endtFi .'6) of this same slot is positioneda fulcrum lock b", loosely f t, said plate lforming a cap to close the end of the slot b', and also preventing endwise movel Lend.y lOne ofthe threads ,fpreferablyf a righteVl handdoublethread,` enga es theblock care mounted upon a ulcrum pin b5, iixedly mounted on the rounding'head B. The two lblock'carri'ers b', bij, are respectively threaded y' internally to receive thedoublethreaded'ad- .usting s crew b (see Fig. 6) mounted atits oft end ma plate 117, secured'to said carrier ment of the 4 double screw while permittingvr free rotation .of the-latter by its squared outer ,rie-g bzlland'is relatively big pitch; s'ay'six to` slide'twoblock carriers b b3, shown best in riphe `shaft 3 (see Fig. 5).. VTo this s ring shaft is attached the inner end of acoi 'or spring d4? attached at its outer end to the interior Wall the inch; While the other thread, also prefiervably a right-hand thread, engages the block b, and is relatively low pitch, for instance twenty-four to the inch; so that rotation of the said screw will cause said block carriers to be moved toward and from each other at varying speeds to cause a peculiar size adjustment that will be better understood later in this description.` The block carriers b, l1, carry respectively the studs t, f b", upon which are loosely mounted the slide blocks b1", b, which are mounted to slide respectively in the right-angled intersecting slots of a rotatable head c (shown inverted in Fig. l1), the slots of said head being marked re- Spectivelyc?, c. and supportedby thehead b, and the one 1s slidable on the other. The slotted head c is provided with afgear c? l(Fig. l) sli htly beveled and driven' by a correspondingly beveled ear c'A on the upwardly inclined shaft c5,

This 'head c is opposed to 3ournaled in the frame'. This-shaft c5.is

driven from the horizontal drive Vshaft a, by a .pair of beveled gears c, c7, mounted respectively Von the said shafts.

f For closing and covering the driving-gear c3 a gear cover cs is provided, which is formed centrally to receive and constitute a bearing for'the upwardly extended gear wheel hea f or hub' c", while the said gear itself is provided with-an upwardly extended ring-like rib c, bearing upon 'and coniined by a depending ribs10X on the said gear cover. The gear cover or casing c8 is secured tothe stationary headB b any suitable means, as

screWss, and providesl a fixed bearing for thev geared head c by means of the circular opening andhub, so that the' only possible motion of. the head c is a rotary one. The gear casing also holds the geared head cv down upon. the carrierb, u on which it is slidably'suportedlgby` the locks b1 and b1?- Both'the cad-)c land the carrier b are thus movably Vslu'iported and coniined between the gear casing c8 and-the stationary head. Removably secured to the hub c is awork supportthe eaded adjusting pihs cl2, surrounded by thimbles cl3, (Figs.` l0 and 10a) which latter carry the worksupport c, upon which is mounted the pattern 015 of metal, Wood, or

The mechanism illustrating my invention provides for both these desirable features,v and to facilitate an understanding of this, I have provided a series of diagrammatic views illustrating the various positions and the various speeds of movement of the solevand cutter one relative to the other. In studying these, however, it must be borne in mind that they are merely diagrammatic for the purpose of enabling the principle of operation to he understood and may not he relied pon as accurate representations of the parts in their various positions, nor as indicating with absolute accuracy the outlines of movements of the parts. The figures are intended to illustrate with substantial accuracy what is above referred. to, and have been plotted as nearly as has been practicable.

.Referring first to Figs. 3 and i2: The parts e shown in plan vienr and diagram in the silions in which Itheywill he found upon tartine' the machine. The pattern is shown' lull lines (Fig. 3) and in dotted lines (Fig. with the cutter in position on the right de and. just forward of' the heel. The circle dicating the outline of the slotted head in i ig. 12 has for convenience been divided into tufo series of spaces or intervals numbered respectively from l to i2; the divisions being equal. and representing in thefollowing eX- planation, regulan distances of rotation of the pattern and machine head, one relative to the other. ln the upper left-hand portion of the ligure is an irregular! and elliptically shaped path indicated by thd long double dot and dash lines and on Whioh are indicated various intervals numberedl from `l to 12. This irregularly shaped path indicates the travel of the free end of the khifecarrier during Aone-half a rotation of the pattermand the numbered intervals thereon, which, it Will -be seen, Yvary in lengt-lli, indicate the 1 travel of that end of the knife carrier upon rotation of 'thepattern during the corre spondingly numbered but equal intervals 'i indios-ted thereon. t

"Ezrarnini d'"now',"the^diagrani (Fig. 12) 130 and assuming that the cutter is in the position marlred l of the diagram, if the pattern. be turned to the rieht, as indicated hy the arrow, through an angle indicated by the in terval 1-2, the outer end olf the 'knife carrier will likewise move through an interval reprei sented on the irregular path by 1--2, which ment of the' pattern from direction, it will be seen, is from left to right,

or opposite the direction of travel of the pattern, which is at the side at which the knife is located generally l'rom right to lett, thus causing an increase in. the speed at which the cutting takes place, as compared with the speed oi cutting if the knife remains station ary and did not move opposite to the pat tern. During the next interval of move- 2 to 3, the tree' end of' the knife carrier on its path moves from. 2 to 3, which is an interval less than the 'first interval 1-2. inasmuch as the interval .9F-3 on the pattern is much longer than the interval 1-2 thereon, the shorter Ainterval 23 of the irregular path of the knife carrer is more than oHset, so that the same or a greater speed of cutting results. the pattern now through a further angle represented by the numerals 3-Ll, would bring it into the position indicated in Figs. 4f and 13 vwith the cutter fairly against the end of the pattern and duringsuch'movement the free end of the knife carrier would have reversed its direction ol travel and moved from 3 to 4 on the carrier path, as indicated on Figs. 12 and 13.

By comparing Fig. 13 with Fig. 12, it will he seen that 'the carrieryreceives at this point only a slight s inging movement abouftthe ulcrum pin b5 as a fulcrurn which causes the f )knife in effect to dwcllfsince the radial distance and the are through which `the knife carrier swings is lesstraveling along the sides oi the sole, conse qiuently in'rounding the heel it willbe seen t iat a very slow cuttingmovement results. During further rotation of the heelend ci the-pattern trom l to free end oi the knife carrier travels from 't to 5 on its indicated path, producing a continu 'ance ol. the swinging movement oi the carrier to cause the same slow movement to continue rounding the second quarter ott the heel from 4 to 5. ln the further rotation oi the pattern llrcm the position Fig. 13 to `that Fig. lll, it will be seen that the 'free end of the carrier continues its swing tothe point 7 and baclr'again to the point 10 to cause 4the knife to have a movement inward and out# ward to follow the natural outline of the sole along the shank, `but leaving it relatively stationary, so far as the feed is concerned, or, moving if at all, ina ,direction opposite that of the pattern to increase the feed along the sideoi' the shoe.' pattern from the position Figli, to

l the patternis ,very much lessened; the knife carrier spring-'may rea The end of the spindle to which the presser carrier is pivoted, is rounded so as toenable said presser to be rotated by and with the vertical spindle e4, yet permit it to `rock on its said pivot to adjust itselt` firmly to and upon the sole blank that is clamped between the presser and the pattern. ipon the top end of the presser spindle e'l'is threaded the adjustable nut e5, circumferentially grooved to. receive the forked short arm of a presser lever e, tulcrumed at e7 in the frame and'having its opposite long arm jointed to one end of the presser rod al. lt will now appear how the upward movement of the said presser rod 0.13X upon depression of the foot treadle, causes the presser spindle to be depressed, thereby to bring the presser into firm holding contact with a sole blank placed upon `the pattern 01". dle e4 is the hub of aslightly beveled gear wheel es, driven by a correspondingly beveled pinion e, liast on the top end of the upwardly inclined shaft c5. Rotation oli the main shaft o thus not only rotates the slotted head c, to produce the movements described of the knife carrier and rotation of the work tableL and pattern, but also rotates the presser in unison with the work support and pattern so that the said work, the presser above it, and the pattern and work support beneath it, rotate as a unit in unison with the beveled gear c3 upon the slotted head c, thus'carrying the edge of the sole past the knife d8, causing the latter, which is always pressed against the edge of the pattern, to trim or round the sole blank to the shape of the said pattern.

With my machine the workman 1s able to stand close to the sole that is being trimmed lor rounded without any large table in front ol' him to cateh anyelothing and cause any damage'. Furthermore, while inthe Julian type oi' machine the cutting action progresses around the periphery' ol' the stationary sole, making it dillicult l'or the operator to l'ollow it with his eye land detect any imperfection in the cutting until al'ter the. sole has been completely rounded and removed, in my niaehine the. cutting takes place always at substantially one and the same point upon which the operators eye may be riveted7 the work passing that point as the cutting progresses.

ly rotatingr the vpresser' as well as the work support, all danger oll the slip ol'A the sole upon the snpj'iortin;y snrl'zn-.es is eliminated.

When the treadle is depressed to start the machine, see Fig. 2, itis caught andheld in its depressed posit ion by lock lever g, de-

Splined upon the presser 'spinpending-:from a fulcrum g on the frame and having its upwardly extendedarm g2 connected by a link g3 with the depending arm of a lever g4 fulcrumed at g5 also on the frame. The upper rend of this lever g4 has a split socket to receive and hold, by means of the clamping screw g, the stem of an eye bolt g7 (Figs. 2 and 3). This eye bolt has adjustably clamped in it the threaded rod gE carrying at its end a cam roller 99 adapted to be engaged at the proper time by a cam g1? (see Figs. 3 and 4). The lock lever g (Fig. 2) is yieldingly pressed to the right to engage and lock the treadle'in its lowest position by a spring gu.

W'hen in the rotation of the rounding mechanism, the sole has been .ompletely rounded, the cam g10 (Figs. 3 and Al) reaches the cam roller gg and throws the same outward, thereby through the mechanism described (Fig. 2) throwing the locking lever g to the left to release the treadle and permit the latter to assume its elevated position, releasing the work and stopping the machine. While the rounding is in progress, however, the clamp and clutch mechanism is held in operative. position, and what is more im ortant, the work is held clam ed quite in Vependently of the operator, so't iat no lack ot attention on his part can effect release of the work until the rounding has been completed. To enable the machine to be operated by hand, whether adjusting or testing it,-in other words, to render it nonautomatic, I have provided the lever g4 (Fig. 2) with a holding dog g, which, when the said lever atits upper end isthrown to the left, may be interposed as a strut between the lever and the head, there to hold it and to prevent the trcadle being locked until again released.

In Fig. 9 l have shown in lull lines a .typ-

ical block sole, such as received in quantityby the shoe manufacturers and from which the sole is to be rounded to pattern shapeand size. These block soles usually present at about'tho point a: (Fig. 5)), a fairly uniform oblique edge; in other words, ordinarily blocked, the two sides of the lore part are substantially uniformly inclined relative t0 the longitudinal median line of the sole, so that whether the solo be a right or a left, the inclination ot the edge at the point :cis substantially the samethough oi` course the length ol' the edge varies according as the sole is a left or a right. l have also found by comparative tests that the desired sole shape at the point usually coincides for a greater or less distance, substantially with the block edge at the saine vicinity,'so that in roundingl the block sole to the desired shape little or no cutting action is necessary in the vicinity ol' the point 1 availy myself of this coincidence to start the cutting mechanism in the vicinity of th point 1n other words,
